Purpose To evaluate implant and prosthetic survival rates of full‐arch rehabilitations retained by three implants in patients with edentulous mandibles. Materials and Methods This systematic review was developed following the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses statement. The focused question was: Are fixed mandibular 3‐implant retained prostheses safe and predicable for full‐arch mandibular prostheses? The Medline/PubMed and Cochrane Library databases were used to conduct the systematic search for clinical trials on fixed mandibular 3‐implant retained prostheses published between 1999 and 2020. Only English‐language studies that presented information on implant and prosthetic survival were included. Results A total of 302 studies were identified, of which 13 addressed the inclusion criteria. Additionally, 574 participants were included in these studies. As reported, 73 (4.57%) of 1596 implants failed, with a survival rate of 95.43%. In addition, the mean survival rate of the presented prostheses was 89.66%. The mean marginal bone loss was 1.09 mm. Conclusion Within the limitations of the present review, implant and prosthetic survival rates of fixed mandibular 3‐implant retained prostheses were similar to those of full‐arch mandibular prostheses retained by four or more implants. Further research exploring the topic is necessary.
